Wisteria floribunda


Wisteria floribunda, common name Japanese wisteria, is a species of flowering plant in the family Fabaceae, native to Japan. Growing to, Wisteria floribunda is a woody, deciduous twining climber. It was first brought from Japan to the United States in the 1830s. It is a common subject for bonsai, along with Wisteria sinensis.
Japanese wisteria sports the longest flower racemes of any wisteria; Some of those cultivars can reach in length. These racemes burst into clustered white, pink, violet, or blue flowers in early- to mid-spring. The flowers carry a fragrance similar to that of grapes. The early flowering time of Japanese wisteria can cause problems in temperate climates, where early frosts can destroy the coming years' flowers. It will also flower only after passing from juvenile to adult stage, a transition that may take many years just like its cousin Chinese wisteria.
Japanese wisteria can grow over long over many supports via powerful clockwise-twining stems. The foliage consists of shiny, dark-green, pinnately compound leaves in length. The leaves bear about 15-19 oblong leaflets that are each long. It also bears poisonous, brown, velvety, bean-like seed pods long that mature in summer and persist until winter. Japanese wisteria prefers moist soils and full sun in USDA plant hardiness zones 5–9. The plant often lives over 50 years.
